Title: Improvements in or relating to methods for carrying out exothermic catalytic high pressure gas synthesis
IPC: B01J8/04
Filed: 1964-02-14
Abstract: In an exothermic catalytic high pressure gas synthesis of ammonia, a stream of reaction gas is passed through a first catalyst bed section in gas synthesis contact with the catalyst, through a second catalyst bed section out of gas synthesis contact with the bed and in indirect heat exchange with a liquid coolant, back through the second catalyst bed section still out of gas synthesis contact with the catalyst, and finally through the second catalyst bed section in gas synthesis contact with the catalyst.  In Fig. 1, <PICT:1057302/C1/1> synthesis gases leaving the upper catalyst layer 2 flow through the annular space between pipe 4 and gas-liquid heat exchanger tubes 6, upwardly through tubes 8 which pass through the lower catalyst layer 5, downwardly through catalyst layer 5, and out at 11.  In the embodiment of Fig. 2 (not shown), the tubes 8 pass into the upper catalyst layer and are then encased in tubes 13 closed at their upper ends, so that the gases are redirected to flow downwardly through the annular spaces between tubes 8 and 13 and enter the lower catalyst bed. The gases leaving at 11 may be passed into a third catalyst layer 12 in heat-exchange with the initial gas mixture. Alternatively, the third catalyst layer may be omitted.

Alternatively it may be arranged above the midpoint of the magnet 1 with its axis of rotation parallel to the longitudinal axis of the magnet 1 so that its plane of rotation is perpendicular to the flux passing through its midpoint. A restoring force is applied to the magnet 3 to oppose its deflection by the field of the pole induced in the body 4 either by a component of the field from the magnet 1 in the plane of rotation of the magnet 3 (when the plane of rotation is at an angle less than 90 degrees to the flux passing through it from the magnet 1) or by a hair spring (where the above angle is 90 degrees). A pointer 14, attached to the magnet 3 to rotate with it, moves over a scale 15 to indicate the distance of the body 4 from the surface 18.

Abstract: 1384573 Substation apparatus; data transmission ESB Inc 16 Feb 1972 [23 Feb 1971]  7173/72 Headings G1U and U18 An arrangement which allows supervision of the operation of a heart pacer or other repetitive signal generator via a communication link includes at the transmitting end means to detect and convert electric signals into transmittable signals and selectively operable means to generate transmittable test signals at a known rate, and the receiving end includes means to detect the frequency of reception of the transmittable signals. As described the transmission end unit 12 can be acoustically coupled to a telephone hand-set 24 and includes two domed electrodes 18 and 30. The electrode 18 can be pressed downwardly against spring action to close a first switch, while the electrode 20 can be lifted free of a receptacle 30 on a base 26 and contains a disc shaped ceramic magnet which closes a reed contact switch in the base 26 when the electrode 20 is placed in the receptacle 30 and when placed on the shin of a patient adjacent a body implanted heart pacer operates a reed contact switch in an intermittently operable pacer or a body synchronized pacer to steady asynchronous pulse generation. The receiving end includes a pulse counter 42 which can be coupled inductively or acoustically to handset 38. In operation the supervisor at the receiving end establishes a telephone connection to the patient and asks him place his handset on the acoustic coupling unit 22 and to press down an the electrode 18 for 10 to 20 seconds. This closes a first switch via the still closed reed switch in the base 26 and enables a 6Hz test oscillator causing it to generate test pulses. Each pulse is amplified and triggers a monostable producing a standard squarewave pulse which is converted into an audible tone pulse and transmitted over the communication line. At the receiver the pulses are counted over a period to test the transmission devices. If these are in order the supervisor can instruct the patient to remove the electrode 20 from the receptacle and place it on the appropriate part of his body so that the frequency of the pacer can be monitored, e.g. to see if the battery needs renewing. Removal of the electrode from its receptacle disconnects the test oscillator and couples that electrode actively to the system.

Abstract: 429,795. Automatic-feed weighers. SIMON, W. G., and SIMON, F. R., Phoenix Works, Vernon Road, Basford, Nottingham. March 7, 1934, No. 7257. [Class 143] In an automatic-feed weigher a lightsensitive cell arranged in the side of the supply hopper arrests the operation of the weigher whenever the level of the material in the hopper falls below a predetermined level. As shown, the cell 6 and an electric lamp 5 are arranged at opposite sides of the hopper and the cell is connected to a solenoid 10 the core of which is linked to a stopping lever 11. The solenoid is energized through a suitable source of power and maintains the stopping lever 11 in the position shown unless the level of material in the hopper descends below the light rays 8 in which case the cell receives the rays and breaks the solenoid circuit allowing the lever 11 to rise and, by engaging an arm 18, lock the feed valve 17 in the closed position. When the material rises and cuts off the rays, the solenoid is re-energized and the operation of the weigher is resumed.
